http://abut.sdsu.edu/TE302/Chap4.pdf WebThis is the simplest way of viewing the frequency spectrum, but it doesn't explain many of the DFT's properties. The lower two figures show how the DFT views this frequency spectrum as being periodic. The key feature is that the frequency spectrum between 0 and 0.5 appears to have a mirror image of frequencies that run between 0 and -0.5.
